Efficiency and Capacity of Coils

Fin tube coils are present in many process heating systems and are typically the first components to show signs of improper filtration upstream. In environments where contamination is an issue, these coils can lead to significant problems, including pump failures, compressor issues, and fan malfunctions. These coils, also known as heat exchange coils, consist of two main parts for heat transfer: the first part is the tubes, referred to as the primary surface, and the second part is...

Thermal Comfort – Section 2

Differences in Thermal Comfort Between Men and Women 1. Introduction Indoor air conditioning is based on experimental models of thermal comfort developed in the 1960s. 2. Metabolism and Standards • Standard values for one of the fundamental variables, the metabolic rate (the amount of energy expenditure and heat production of each individual), are determined based on the metabolism of an average man. • This value is 35% higher than the predicted basal metabolic rate of an average woman. 3. Women's Metabolic Rate • According to recent findings,...

Types of Condensers

Main Concept: Condensers operate based on the principles of heat transfer, which involves the movement of heat from warmer environments to cooler ones. The functioning of a condenser involves three basic phases: Phase One: Desuperheating In this phase, the highly heated and pressurized refrigerant vapor entering the condenser first loses its heat. This process aids in the initial cooling of the refrigerant. Phase Two: Condensation Once sufficient heat has been removed from the refrigerant vapor, the condensation process begins. In this...

Differences Between Refrigerants R22 and R410

Refrigerants R22 and R410 are two types of gases commonly used in air conditioning systems. These two gases are compared due to their different characteristics and environmental impacts. Below, we will examine the key differences between these two gases.

1. Environmental Status

R22: It is a hydrochlorofluorocarbon (HCFC) that harms the ozone layer. For this reason, its production and use have been banned in many countries. R410: It is a hydrofluorocarbon (HFC) introduced as a more environmentally friendly alternative to R22 and has...

Key Points for Maintaining Chiller Evaporators

1. Installation of Strainer in the Water Inlet to the Chiller Evaporator Installing a strainer in the water inlet to the chiller evaporator is essential and offers numerous benefits: • Prevention of Suspended Particle Ingress: The chiller evaporator, being a sensitive component of the heat exchange system, is susceptible to damage from particles like sand, rust, and debris. These particles can reduce heat transfer efficiency and cause blockages in the system. • Difficulty in Cleaning After Contamination: Once contaminants enter, cleaning the evaporator can be...
